LIME CARTRIDGE.

' .SPECIFICATION forming part of Letters Patent No. 532,993, dated January 22, 1895. Application filed October 8, 1894. Serial No. 525,251. (No'modeh) residing at Darcy Lever, in the county of Lancaster, England, have invented Improvements in Lime Cartridges for Breaking Down Coal,

Rock, and other Minerals, ofwhich the following is a specification.

This invention applies to that class of cartridges employed forbreaking-down coal, rock,

and other minerals, known as lime carftridges, wherein the rending action of the coal or other mineral is produced by the admission of water to the compressed lime, the

latter swelling or increasingrapidly in bulk by the absorption of. the water and thus rending asunder the coal or other mineral.-

The nature of. my said invention and the.

manner in which the same is to' be performed or carried into practical effect will be readily understood on reference tothe annexed sheet of drawings and the following explanation thereof. l I v Figure-I is a transverse section and Fig. 2'

view, and Fig 4 a partial sectional elevation of a modification thereof hereinafter more particularly described. According to my invention so as to leavea hole 12 extending down through the center of the lime from one end tothe' I compress the lime into the form of a cylindrical cartridge'a other (or nearly so) whereby the water is introduced at once into about the center of 'the' In addition to the central hole, I make longitudinal shallow grooves or channels, as shown at 0, Figs. '3 and 4, on the outside of the lime, in order to faciliate the simultaneous access of-the-waterto the outside of the cylinder In the cartridge shown at Figs. 1 and 2, in addition to making the compressed lime cylinder a with a central hole I) I providethe same with longitudinal passages or flattened spaces at radiating outward from the central hole 6 and extending from end to end of the cylinder a or nearly so. The object of these additional radiating spaces is to faciliate'the rapid dis tribution of the water or acidulated water to the whole mass of. the lime'when it is forced into the central hole I) by the pump.

In the modification shown at Figs. 3 and 4, in addition to the central hole I) I make several auxiliary holes I) surrounding the central hole, and I connectthem therewith by longitudinal flattened spaces d radiating from the centralhole b to the auxiliary holes b, and at the ends of the cartridgeI make shallow channels e connecting the holes b and I) together.

0 outside the cylinder a 7 By thesetwo me hods the water or acidulated. water is dist ibuted, as regards Figs. 1 and 2, longitudinally through the center of the cartridge and radially into the interior of the mass; and as regards Figs. 3 and 4, it is distributed first centrally into the hole 19 then radially along the'passages d to the-auxiliary holes 19' and thence at the ends along the shallow connecting channelse tothe long'i-tu dinal grooves 0 outside the cylinder, so that the water or acidulated water acts simultane- I ously on a great surface of the lime cylinder,- the effect of this being to hasten the operation ofbreaking-down the coal or other mineral.

a longitudinal section of my improved lime cartridge in its simplest form. Fig. 3 is anend I claim as my invention- 1. A lime cartridge'having a central'hole and with thelongitudinal channels or grooves and internal radiating passages, the said hole and passages extending longitudinally through the cartridge, as and for the purpose set forth. 7

' 2. A lime cartridge having a central long-i.-

itudinal hole, auxiliarylongitudinal holes '1) and internal radiatiugpassages also extend i'ng longitudinally through the cartridge, as

and for the purpose set forth.

3. A lime cartridge'havmg a 'central'hole external grooves c and internalradiating passages, the said hole, grooves and passages extending longitudinally through the cartridge and radiating chan nels e at the end ofthe car-I tridge leading to'thegrooves substantially" as set forth. In testimony'whereof I havejsigned my name to this specification in the presence of two subscribing witnesses.
